I think lack of focus on US domestic chip capability is semi-intentional and is an eventuality. Semiconductor industry, and many other manufacturing industries too, seem to flourish at very outer edges of the free world.
It could be simple as the free world not wanting manufacturing capability at home. It could be wanting only grain farms and money printers.
Manufacturing in the west is expensive compared to cheaper developing countries.
Also, manufacturing has a massive impact on the environment, this includes semiconductor manufacturing. It has politically been impopular for a while now.
Because of the resource curse - everything that isn't the best cost/benefit ratio to a country tends to become unworkably expensive. The USA's cursed resource is money - literally - it prints the world reserve currency.
